Be it imownthat I, Ouaris B. may; a. citizen'oi the Unitedlstatee,residing at New. Haven, in the county of New Haven and State ofConnecticut, have invented a newand useful.ImprovementinPneumstic Tires;I and I do herebydeclare the following, when taken in connection withthe accompanying drawings, and the letters of reference marked thereon,to be a full, clear,

' resent, in

and elxact-des cription of thesame, and which said drawings constitutepart'of this specification, and rep- Figure 1 a sectional view of a tireconstructed in accordance with my invention; Fig. 2 a brokenlongitudinalsection showing the corrugations in the rim and plates. Fig.3 a broken sectional-view illustrating the modified form of rim.

. This invention relates to an improvement in pneumntic tires andparticularly to such as guard or protect the infiated'or pneumatic tubeso as to prevent the puncturing thereof by contact with any sharp edgepassing through the outer tire, the object being a simple arrangement ofparts which permits of ready access to' the inner pneumatic tube, whichpositively prevents any edge cutting the tire from touching the innerpneumatic tube and which, furthermore, provides a tire which may berunwith safety should the pneurustic who become deflated; and the inventionconskate in the construction as hereinafter described and particularlyrecited in the claims. H 1 In carrying out my invention I employ twoplates 2, 3, the plate 2 having arm's slightly wider-than half thewidthoi the ielly 5 towhich it is-attached by bolts '6, while the plate3 has a base 7 which is connected with the base 4 by bolts 8 so that theplate 3 may be readily removed. These plates extend outward from thebase and thence inward, and the inner faces!) and 10 stand parallel witheach other. Located between the faces 9 and 510' and fitting thornclosely is au'iuwardly opening archedrim 11 the inneredges 12 being.rounded. On each side at the outer edge the rim: is

formed with -horizontally extending flanges 13, and

' formed with similar'corrugations 17 for the purposeas will hereinafterappear. The outer tire 18 is secured to the rim 11 in any preferred way,but if the rim isprovided with the dovetailed ribs 14 as described, thetire will have correspondinggrooves 19 to interlock therewith: The tire,which is substantially semicir-' cular in cross section, hasat its edgesinwardly turned lien 0 tegminating in ribs 21 which set grooves 22Specification of Letters Patent.

gaged witli said rim and connected with said Patented July 9, 1907,

formed in the outer faces of the upper ends oi-the,

plates 2 and 3, and these ribs arelocked in engagement "with the'plates-by clenchers 23 secured tothe plates 2 and 3 by screws 24 atthat by removing the cleuchers 23 the outer tire may be removed. Betweenthe plates and within the-rim 11 is the usual pneumatic tube 25.

If thispneumatic tube be inflated, it will force the I rim 11 out ard,and hence hold the tire in an extended position, the arch of the rimproviding ample space tenths-expansion of the inner tube. 'The rim beingof metal and bearing against. the faces 9 and 10 of the plates willrea'dily slide therein as the pneumatic tube is compressed, and willgive s'ufficient rigidity tothe outer 'tire to prevent its rocking.Should the inner pneumatic. tube become deflated the rim 11 will, as

the wheel revolves, be iorced' inwardbetween the plates so'that theilanges13 bear upon the outer edges 15 oi,the plates, and if so, thecorrugations 16 and 17 willin'terlock' and prevent the tire fromcreeping, and

at the same time. give a sufficientbearing so that the 7 vehicle may berun without danger .of cutting the tire. 1 By removing the clenchers 23the tire may be readily replaced, and by removing the plate 3 readyaccess may be had to the inner pneumatic tube should it be necessary torepair or replace it,

Instead of having the rim open inward as shown in Fig. l oi thedrawings, it may be reversed, as shown in Fig. ,3 of the drawings, inwhich case the central portion 26 of the tire may extend down into therim. and the inner face of the rim will bear upon the inner pneumatictube so as to protect the same as effectually as before described.
